The Case for Increasing Australia's Goods and Services Tax
Reforming the tax mix could address long-term debt and demographic shifts effectively.
1Political Resistance to Reform
Politicians avoid proposing GST increases due to electoral risks, preferring short-term political safety over structural fiscal fixes. Despite support from figures like Josh Frydenberg and Paul Keating, no major party has committed to raising the rate from 10 percent to 15 percent, leaving the national tax system stagnant and increasingly outdated.
2Unsustainable Debt Trajectories
Australia’s public debt has surged from 5 percent of GDP two decades ago to 45 percent today. With global interest rates rising, debt servicing costs are poised to consume a larger share of the federal budget, making current deficit spending patterns unsustainable and necessitating a shift toward consistent budget surpluses.
3Declining GST Revenue Efficiency
The GST has failed to keep pace with economic growth over the last 26 years, leading to an over-reliance on income tax. This dependency triggers bracket creep, which disproportionately affects taxpayers. Expanding the GST base or increasing the rate is viewed as a necessary correction to diversify federal revenue streams.
4Addressing Regressivity Concerns
Critics argue that increasing the GST is regressive, yet this can be mitigated by simultaneous income tax cuts and welfare adjustments. International comparisons show that most OECD nations utilize value-added taxes at rates significantly higher than Australia’s 10 percent, suggesting that a 15 percent rate remains well within global norms.
5Demographic Shifts and Aging
The retirement of the Baby Boomer generation combined with declining birth rates threatens the sustainability of the current tax model. Fewer working-age individuals are left to fund pensions and healthcare for the elderly, creating a structural imbalance that necessitates shifting the tax burden toward consumption-based models like the GST.
6Grattan Institute Reform Proposal
A proposed model suggests raising the GST to 15 percent while removing food exemptions to generate $76 billion annually. This plan allocates $33 billion for income tax cuts and $25 billion for welfare increases, ensuring low-income households are compensated while higher-income earners contribute more to the overall tax pool.
7Impact on Household Finances
Under the Grattan model, a low-income single-parent renter could be $150 per week better off due to increased welfare payments. Conversely, higher-income working families would face a net increase in tax contributions of $162 per week, effectively rebalancing the system to favor those with the least financial capacity.
8Long-term Fiscal Stability Goals
While tax reform improves fairness, it does not automatically balance the budget or reduce public debt. Achieving true fiscal health requires additional measures, such as capturing more profits from resource exports. Reducing debt is essential to provide the government with necessary flexibility during future economic recessions or global health crises.
